If in doubt, ask (the engineer to provide you with a detail).

Maybe to you but not in these current days of biodiversity and ecological enhancements. Look on the LPA’s website for other similar schemes so you will get an idea as to the level of detail required.

What jurisdiction does the BCO have over a Planning condition?

If it does not specially state ordnance datum levels, then set your own starting with 10.000m for example.

Which would have different requirements than a single storey (bungalow) dwelling. The number of storeys dictate the means of escape requirements.

Is yours a single, two or three storey dwelling?

Yes, correct and makes sense. Different obligations and requirements but both enforced by the relevant LPA (where applicable).

The CIL paperwork itself a charge on the property/site. Some LA’s may ask applicants to enter into a separate legal agreement, but definitely not all.

Many more than two things. It has to comply with Class E of the GPDO.

That would be a lot of work and cost for what I see as minimal gain. Remember the newly extended part would have to comply with the current thermal regulations. That may well impact internal and external wall and roof lines not lining through with the existing dormer.

As above, search for traditional character properties for inspiration. ChatGPT can also be quite helpful.

The author then 😄

And if there is not an Architect?

🤔

The author owns the file(s). The fact you have fallen out with your Architect, I cannot see them sharing any files with you.

So was the report mentioned in the Pre-app response (as per your original post) or Outline Approval with conditions decision notice? If the latter, you have no choice but to submit one. The Outline Approval would take precedent over the Pre-app response.

Do you already have outline approval then?

What are you proposing? If it is required as part of the validation process, then it will be needed to be provided upfront.

The 30sq.m doesn’t have anything to do with Planning. If you have Class E PD rights and the outbuilding complies with the PD requirements, then Planning would not be required. You could submit a Lawful Development Certificate application to confirm it is PD.

It depends upon the overall design and character of the property along with the local area. If you’re having flat ceilings internally, those eaves heights will provide you with internal ceiling heights of around 3.15-3.65m.

Traditionally, eaves would be a minimum of 2250mm above ground level (2100mm above DPC) and a minimum roof angle of 35 degrees. But there is a lot more to the design than that. It sounds like you will need to engage an architectural designer.

It depends upon the LPA.

Have a search on your LPA’s website for DoC applications and you will see what is uploaded. The uploaded information is not that dis-similar to that of any other application. It’s in the public realm.
